PAL to NTSC

Is it possible to convert PAL into NTSC???

(without loosing quality, off course)

Can VDubM do that?

Nah, forget about it.

I found something that would work.

okay well for others who just come across this topic you could use avisynth (just open notepad, enter these lines and then rename the extension to .avs)

If you want to convert PAL to NTSC enter:

changefps(29.97)

or

changefps(30)

and for NTSC to PAL just enter:

changefps(25)

but remember the first line should state where the file is located.

P.S I know this should be in the AVIsynth section but its just 1 way to convert PAL to NTSC (well the easiest without converting).

If it's for DVD, just encode as 25fps and use DGPulldown. Although I don't do that, but it's an option.

There's ADTelecine (I think it can do PAL->NTSC), or the ChangeFPS(29.97) line mentioned above. However, converting from NTSC to PAL by doing a ChangeFPS(25) isn't as clean, as it has to drop frames instead of add them. Thus, to preserve motion - at the expense of blending - using ConvertFPS(25) would probably work better.

Otherwise, IVTC the 29.97 footage, and do AssumeFPS(25,sync_audio=true).SSRC(48000,fast=false) - but be aware it'll make the audio higher or lower-pitched, and if the footage is meant to be in 29.97 instead of 23.976 you're SOL when the IVTC messes up your motion.
